TUBAL RECANALIZATION
TUBAL RECANALIZATION (FALLOPIAN TUBES)
Tubal recanalization is performed in women who have had a tubal ligation. It is done through surgery to reconnect the tubes and is performed under anesthesia. Recanalization surgery is recommended if:
The woman is under 35 years old
It has been less than 10 years since the ligation was performed
Her partner has a normal sperm count
The success of recanalization depends on the woman’s age and the type of ligation performed, as in some cases tissue loss makes it difficult to reconnect the tubes and achieve pregnancy.
DEFERENT DUCT RECANALIZATION
Deferent duct recanalization, or vasovasostomy, is a microsurgery aimed at reversing a vasectomy and restoring male fertility.
It involves reconnecting the ducts that carry sperm, allowing their passage into the semen.
It is indicated for men who wish to have children again after a personal decision, a new relationship, or the desire to expand the family. The surgery lasts between 2 and 3 hours, is performed under anesthesia, and the patient can return home the same day or the following day.
The first semen analysis is performed at 8–12 weeks, with subsequent follow-up. The success rate depends on the time since the vasectomy: if it has been less than 10 years, the probability of recovering sperm is 80–95%; after 15 years, it drops to less than 60%.
The chance of natural pregnancy ranges from 30% to 75%, also influenced by the age and fertility of the partner.

Frequently Asked Questions
about recanalization
1. What is tubal recanalization and in which cases is it recommended?
It is a surgery to reconnect the fallopian tubes after a ligation. It is recommended if the woman is under 35 years old, the ligation was performed less than 10 years ago, and her partner has a normal sperm count.
2. What does the success of tubal recanalization depend on?
It mainly depends on the woman’s age and the method used for the ligation. If there was significant loss of the tube, it may be difficult to achieve reconnection and pregnancy.
3. What is deferent duct recanalization or vasovasostomy?
It is a microsurgery that reverses a vasectomy by reconnecting the deferent ducts to allow sperm to pass into the semen again.
4. Who can undergo a vasovasostomy?
Men who wish to regain their fertility after a vasectomy, whether due to personal decision, a new partner, or the desire to have more children.
5. What is the recovery time and follow-up after a vasovasostomy?
The surgery lasts between 2 and 3 hours under anesthesia. The patient can return home the same day or the next and should maintain relative rest. A semen analysis is performed between 8 and 12 weeks to evaluate the results.
6. What factors influence the success of a vasovasostomy?
The time since the vasectomy is key: if performed within 10 years, there is an 80%–95% success rate in recovering sperm. After 15 years, the rate drops to less than 60%. The probability of natural pregnancy ranges from 30% to 75%, depending on the female partner’s fertility and semen quality.
